vTo alltohowt'it'm'aycncrn: n f Be itfknown'that LTHoMAsiKEMrLAY IR- ,fwm, subjecnofjiiis Majesty the King of England ,residing at5 London ',-Wall'Buildkings, inthe city of London, lKingdom of Englandhave inventedcertain new and use- Afin-improvements? in or Relating to Hydro- `Extractors or like Centrifugal Machines; of

whichthe following is a specification.

This invention relates to improvements in hydro-extractors or like Y centrifugal ma.-`

chines. Y Where' such machines .arelused' for thefclarificationf or other .treatment lof liquidsgor the. removal of quantities 'of liquid fromfsolidmatters, av considerable amountv 'i of thelpowervrequiredfor operating'them is absorbedyin .raising .the lqudto therspeed l of "the rotating cageandpthen discharging it.`V `'In' order to obviate this waste .of power it has rpreviously vbeenv proposed to cause the liquid as it leavesthe vmachine to `operate reactively yso as toeXert al drivingforce on n lth'e inachinein the safe ,direction as the apyplied,power. It has alsofbeen proposed to obtain'f'similar i results' by providing the: :machine ywith turbine like blades. for.v the exit,A of the .liquid,. 4Now accordingv to theipre'sent linvention I luti-lize this waste power by causy ingthe` liquidi-as vit escapesffrom the' cage,V 3() L to f toplerate 'y a1 separate y impulse v.rotor fwhich lmay nits turn,"operate a second centrifu- -'ga'l*m'achine either directly or through the .medium lof vishafting,k electricity, or other 'known-[zmethods of transmission; or the ,fpowerfmaypif desired be utilized for any ffotherv'convenient purpose. VVhere very large machines are yto be used` and considerable powen-is required ."for-gtheiroperation, a
